Answer:
12.29 M
Explanation:
- The reaction that takes place is:
H₂SO₄ + 2NaOH → 2Na⁺ + SO₄⁻² + 2H₂O
- Now let's calculate the <u>moles of H₂SO₄ that were titrated</u>:
= 0.01229 mol H₂SO₄.
- Thus, the <u>concentration of the diluted solution is</u>:
0.01229 mol H₂SO₄ / 0.010 L = 1.229 M
- Finally, the <u>concentration of the original acid solution is:</u>
= 12.29 M
Answer:
electron, proton, nucleus, atom, molecule teacher
The correct is tricky, be careful. The right is silicon dioxyde (SiO2)
Silicon Oxides are written in the form SiOx, (0 <x <2), so:
there is no silicon trioxygen and disilicon dioxygen.
SiO is called silicon monoxide and not monosiicon oxygen, so this proposition is false.
All that remains is the silicon dioxide (SiO2) that is written correctly.
Silicon dioxide can be synthesized but also exists in abundance in nature. Silicon (Si) represents about 26% of the Earth's crust. Silica (SiO2), the natural form of silicon dioxide, accounts for about 60%.
false, the rusting of iron can be prevented by painting, oiling, greasing or varnishing its surface.
